ANNUNCIATOR.

SPECIFICATION forming part of Letters Patent N. 765,037, dated July 12,1904.

Application filed February 28, 1903. Serial No. 145,556. (No model.)

To (LM whom zit may concern.-

Beit known that LPATRICK OOoNNoR, a citizen of the United States,residing at Au gusta', in the county of Kennebcc, in the State of Maine,have invented a new and useful Improvement in Annunciators, of which thefollowing is a specification.

This invention relates generally to annunciators, and more particularlyto that class thereof known as electric annunciators employed in hotelsand elevators for the purpose of indicating the particular locality fromwhich the signal is sent.

The object of my invention is to provide an exceedingly cheap, simple,and eilcient construction of annunciator which will be safe and accuratein operation; and with these objects in view the invention consists inthe novel features of construction, combination, and arrangement, all ofwhich will be fully described hereinafter and pointed out in the claim.

In the drawings forming part of this speciiication, Figure l is aperspective view of an annunciator embodying my invention, a portion ofthe front of the case being broken away to disclose the interiormechanism. Fig. 2 is a sectional view of the case, the mechanism beingshown in elevationand showing the indicator resting in an inoperativeposition. Fig. 3 is a similar view showing the indicator chopped for thepurposeof indicating the station sending the signal. Fig. 4 is a detailperspective view of the bracket. Fig. 5 is a detail perspective Vview ofthe indicator and rod. Fig. 6 is a detail perspective view of thearmature and parts connected thereto. Fig. 7 is a diagrammatic viewdrawn through the front of the casing, the means for resetting theindicators being shown in elevation.

In carrying out my invention I employ a case A, having the glass panelA', which panel is made opaque, with transparentvportions A2 at regularintervals, there being as many transparent portions as there areindicators to be arranged in the case, and it will of course beunderstood that any desired number of indicators may be arranged in onecase as desired, and in the drawings I have shown acase constructed forseven indicators, so that the aununciator can be arranged in an elevatorfor a building having seven floors, or the said annunciator may bearranged in a hotel-oiiice having seven diierent signal stations orrooms.

It will of course be understood that the use of my invention is notlimited; but the device may be employed inany connection where it isdesired to operate an indicating-signal which will remain exposed untilreset. Inasmuch as each indicator is operated by thc same mechanism, adescription of one indicator and the operating mechanism will suflce forthe description of the entire annunciator, and in constructing anannunciator in accordance with my invention I employ a bracket B,comprising a back plate B'and a forwardly-projecting hori- Zontal armB2, said arm having a vertical guiding-sleeve B3 extending downwardlyfrom its forward end, and adjacent to said forward end are theupwardly-projecting angular lugs B1, having openings B5 producedtherein. The electric magnet C is attached to the back plate B', saidback plate being rigidly connected to the rear of the case, as mostclearly shown in Figs. l, 2, and 3, and the armature D is pivotedbetween the annular ears or lugs B* by means of a pivot-bolt D', whichextends through the barrel portion D2 of the armature and through thesaid ears or lugs. Sliding in the guide B3 is a rod E, carrying anindicating-target F at its upper end, bearing a numeral indicating thestation from which the sig'nal is sent. The guiding-sleeve B3 has apolygonal-shaped bore, and the rod E is correspondingly shaped incross-section to prevent the turning of the rod.

A notch or recess E is produced in the rear face of the rod, adjacent tothe upper end, which notch or recess is adapted to be engaged by a noseD3, carried by the armature at its upper end, a spring D4, carried lbythe armature, serving to throw the said armature into engagement withthe notched rod when said rod is elevated. When the magnet is energizedand the armature attracted, the nose D3 is withdrawn from the notch E',and the rod E, with the indicator F, will drop until the indicating diskor target rests upon the top of the guiding-sleeve, as most clearlyshown in Figs. 1 and 3, and at such time the indicator will bc broughtdirectly opposite its respective transparent portion A2, thereby eX-posing the indicating-numeral. In order to reset the device after it hasonce been operated, I employ a push-rod G, having' a knob Gl at itslower end, the upper end of said push-rod passing' upwardly through thebottom of the case and through a guide G2 and carrying an openrectangular frame comprising' the horizontal member G3, which extendsalong and normally rests on the bottom of the casing, being directlyunder the rods E and the upright members G1, which slide in eyes G5,secured to the ends of the casing, the lowest eyes also acting as stopsfor the member G3. By pushing upward on the rod G the member G3 islifted vertically, carrying with it any rod E which may have fallen, andas soon as the notched portion E passes the nose carried by the armaturethe spring EJL will operate to throw the said nose into engagement withthe notched rod.. rlhe rod E has a stop-pin E2, servingto limit theupward movement of the indicator.

It will be obvious that if the indicators F were arranged one above theother instead of side by side a plurality of bars could extend from onemember G4 to the other, said bars being one above the other.

It will thus be seen that I provide an eX- ceedingly cheap, simple, andeicient mechanism capable of performing all o' the objects hereinbeforementioned.

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent, is-

A device of the kind described comprising'- a bracket consisting of aback plate to which the magnet is attached, a forwardly-projecting armhaving upwardly-projecting ears between which the armature is pivoted, anose carried by the said armature, a depending guide-sleeve arranged atthe forward end of the horizontal arm, a rod sliding in said sleeve andhaving a notch adapted to be engaged by the nose on the armature,anindicator arranged upon the upper end of the rod, and a pushrod forresetting the indicator, said indicator and push-rod having'stop-pins,for the purpose speciiied.
